IB Chemistry Experiment 4 Composition of a Post-1983 Penny Lab Report Background: Through the use of percent composition one can easily find out how much of a certain element is in a compound or an item such as a post-1983 penny. The experiment will be using HCl a strong acid to dissolve all the zinc inside the outer copper shell. The reaction follows as such; Zn+2HCLZnCl2+H2‚ but there will be no reaction with copper. The portion that will be measured is the mass of copper left after all of

253- TA: Gia Hoang Lab 1: Effect of pH on a Food Preservative 9-1-2011 Purpose The purpose of this lab was to determine if a new substance forms when sodium benzoate is placed in a simulated stomach acid. Theory Benzoic acid can be found in a wide variety of plants. It is used as a natural preservative in many foods. Sodium benzoate‚ the salt of benzoic acid‚ has become a more popular choice as a food preservative because it is more soluble in water than benzoic acid. Many food items found

Sodium‚ one of many elements in the periodic table is being used in everyday life‚ it is also an essential element within your body. It is just another element‚ but one of the differences is that this element is something that most people consume every day. Sodium has played an important role in everyday life because of its uses in medicine‚ industry‚ and agriculture(Shriver). Sodium was discovered in 1807 by a man named Sir Humphrey Davy. He was well known for his discoveries of most alkali metals
